Undisclosed, luckily there is very little physical addiction, but there is unfortunately a substantial amount of psychological addiction. The best would be to find someone you can trust to help you through the rough spots when the craving becomes to big to handle on your own. That said, most people that decide to quit coke don’t start using again because of withdrawal symptoms or cravings, but rather because of the depression that sometimes follows the initial withdrawal phase. You can sidestep this be asking your doctor for an antidepressant like Cipramil® or Aropax® as soon as you start feeling gloomy/depressed. Good luck.
